Exponential Growth & Decay

What is Exponential Growth?

Back

Exponential growth occurs when the increase in a quantity is proportional to its current value, leading to growth that accelerates over time. Example: If a population of bacteria doubles every hour, it exhibits exponential growth.

What is Exponential Decay?

Back

Exponential decay is the decrease of a quantity at a rate proportional to its current value, resulting in a rapid decline. Example: A radioactive substance decaying over time is an example of exponential decay.

What does the base 'b' represent in an exponential function?

Back

The base 'b' in an exponential function indicates the growth or decay factor. If b > 1, the function represents growth; if 0 < b < 1, it represents decay.
